GAS-STOVE.

Specification of Letters Patent. Patented Sept. 19, 1916.

Application filed December 16, 1914. Serial No. 877,517.

To all whom it may concern Be it known that I, EDWARD G. GnnMnn, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented new and useful Improvements in Gas-Stoves, of which the following is a specification.

This invention relates to gas stoves and consists in certain improvements in the coin struction thereof as will be hereinafter fully described and pointed out in the c aims.

More particularly the invention relates to heating stoves. In these stoves as ordinarily marketed there are three principal considerations, namely: the eili-ciency of the store as a heater, its appearance or artistic etl'ect especially when the stove is in use, and the protection from inunediate contact with the flame.

The present invention is directed to improving a stove along these different lines as well as the details of construction which will appear more fully from the specification and claims.

The invention is illustrated in the accompanying drawings as follows:-

Figure 1 shows a front elevation of the stove, a part being broken away to the section line 1-1 in Fig. 2. Fig. 2 a section on the line 2-2 in Fig. 1.. Fig. 3 a section on the lines 3 3 in Figs. 1 and 2.

The stove frame or case as shown is formed of sheet iron. It has a rear plate 1. The sides of the frame are formed from the same plate as the rear by bending the sides of the plate forming the back forward. The front edges of the sides are bent inwardly and the front plate 3 is secured to these edges in any convenient manner. The front plate has an opening 4 for the reflecting plate of the stove hereinafter referred to. A. dish-shaped bottom plate 5 is provided and has openings 5 for the admission of air around the edges. A top plate 1* forms a joint with the top edges of the back, sides and front of the frame.

A burner 6 extends from side to side of the stove. It terminates in a mixer 7 and an ordinary gas valve 8 is arranged at the end of the mixer. A fire back 9 is arranged directly back of the burner. This is support ed by a metal plate 10 which extends across the stove. It has the lips 1O at the top and bottom which secure the the back and the flanges 1O at the ends'which are secured to flue plates 12 at each side of the stove. A baille plate 13 is arranged diagonally above the burner and extends from the top of the opening 4 to the upper part of the rear plate 1. It extends sidewise to the flue plates 12. The baflle plate 11 extends be tween the flue plates 12 and from the top ballle 13 downwardly. The gases pass from the burner along the fire back and then are dcllected by the plate 13 to the passage be tween the rear of the plate 10 and the battle ll. The gases then pass upwardly along between the baille ll and the rear plate 1 and are discharged through an opening 15.

The lire back has a series of projections 16. The burner has a series of jet openings 17 extending entirely along the tire back. Adjacent to each projection 16, however, there is massed added jet openings 19 so that the mass of lame envelops the projection 10 thus heating these projections to an incandescent state. The fire back is prcferably of material, ordinarily the brick which will readily glow under heat. By extending the jets along the burner the burner may be lighted through the lighter opening 20 at the side of the stove, the ignition being carried along by the jets 17.

A plate 21 is arranged under the burner and forms an air chamber 22 at the bottom of the stove the ends of this air chamber connnunicating with the flue Ql formed be tween the line plate 12 and the side 2 of the stove. Air passes by the line 34. to the chamber 25 formed above the battle plate 13 and thence out of openings Ll) in the top of the stove. Openings are arranged in the plate 21 directly under the burner so as to supply air for combustion.

A reflecting ')late 27 is arranged in the opening i. This plate has a surrounding flange 28 and a depressed or inwardly extending portion 29, thus forming side walls 30, top wall 31 and bottom wall 3?. The rear wall of the plate 27 has vertical slots 33 and the top and bottom walls hare semicircular openings 31' directly in front of the slots 33. Pellucid closure pieces 35 are arranged in front of the slots These are inserted by slipping the closure pieces upwardly in the slots ill in the upper wall 31 and then lowering them into the openings Illin the lower wall 32. The rear edges of the closure pieces when in place rest against the front face of the rear wall and are out of contact with each other, leaving a strip of the plate 27 visible between them. The pellucid pieces 35 rest on the platform 21 this being an upwardly bent portion in the plate 21. Openings 36 are arranged in the platform 21' directly back of the pellucid pieces These pellucid pieces are curved and formed of glass having the outer surface ground so as to give a tanslucent as well as pellucid effect, thus the incandescent glow of the projection 16 is communicated from the pellucid pieces giving a very pleasing effect. At the same time a complete closure is provided for protection against the flame. The plate 27 is preferably of white enamel both for appearance and for its effect as a reflector. The air passing up throu h the openings 36 insulates the pellucid pieces sufficiently to prevent their be ing so intensely heated from the burner as to crack the glass. The stove is very eflicient as a heater both by reason of the direct action of the gas and air and the reflection from the incandescent portions.

Vhat I claim as new is:-

1 In a stove. the cmnbination of a gas burner: an inclosed front comprising mem bers of rigid pellucid material curved with a vertical axis and outstanding from the portions of the front immediately adjacent to the edges of said members, said members being open toward the burner; and means for establishing a current of insulating air along the inner surfaces of said members.

2. In a stove. the combination of a burner; an inclosed front comprising a metal plate having vertical slots therein and a closure piece of pellucid rigid material bridging said slots. said closure piece being curved with a vertical axis and protruding from said plate; and means for establish ing a current of insulating air along the inner surface of said closure piece.
